Abstract

The present invention is a device and apparatus to protect a welder's eyesight, including a protective shield in a window frame, the frame having a pivotable slotted flange acting as a socket for a rotatable wire rope anchor connected, through the flange, by a wire rope to an automatic or manual, remotely operable actuator. The actuator can be conveniently mounted to welding equipment, such as a cutting handle, using an interchangeable base. The base has means for attachment to the cutting handle, and means for removable and/or adjustable attachment to the actuator device using interlocking mounts. The invention further includes a means to inhibit energy flow to welding equipment while the vision-protecting window is open.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. An eye protection device, comprising: 
       a window frame coupled to a housing unit;  
       a slotted flange pivotally coupled to the window frame;  
       a wire rope anchor captured by and in rotatable opposition to the slotted flange;  
       a wire rope extending through the slotted flange and coupled to the wire rope anchor; and  
       a window frame actuator coupled to the wire rope.  
     
     
       2. A safety apparatus for welders, comprising: 
       a window frame coupled to a housing unit;  
       a curvilinear slotted flange pivotally coupled to the window frame;  
       a first anchor rotatably coupled to a wire rope, the first anchor being captured by, and in rotatable association with, the slotted flange;  
       the wire rope coupled to the wire rope anchor through the slotted flange; and  
       a window frame actuator coupled to the wire rope and mounted to a base, the base affixed to a welding tool handle.  
     
     
       3. The apparatus according to  claim 2 , further comprising interlocking tapered bars slidingly connecting the window frame actuator to the base. 
     
     
       4. The apparatus according to  claim 3 , wherein the window frame actuator is adjustably mounted to the base. 
     
     
       5. The apparatus according to  claim 4 , further comprising an adjustment pin disposed between each of said tapered bars. 
     
     
       6. The apparatus according to  claim 5 , wherein the number of tapered bars is at least two on each of the actuator and the base. 
     
     
       7. A safety apparatus for welders, comprising: 
       a window frame coupled to a housing unit;  
       a slotted flange pivotingly coupled to the window frame;  
       a first anchor rotatably coupled to a first end of a wire rope, the first anchor captured by, and in rotatable association with, the slotted flange;  
       a wire rope actuator coupled to a second end of the wire rope, and the actuator also coupled to a welding tool handle, said actuator further comprising; and  
       a window frame actuator coupled to the second end of the wire rope, and to the welding tool handle, said window frame actuator further comprising:  
       a second anchor coupled to the wire rope;  
       a lever having a first end connected to a finger plug; and  
       a slotted socket formed within a second end of the lever for guiding the rope wire, and for rotatably receiving the second anchor.  
     
     
       8. The apparatus according to  claim 7 , wherein the slotted socket has a spherical interior surface. 
     
     
       9. The apparatus according to  claim 7 , wherein the finger plug is fitted with a safety sensor which controls the energy to a welding tool. 
     
     
       10. The apparatus according to  claim 7 , further comprising a worm screw connected to the wire rope, the worm screw slidingly rotatable relative to the second anchor. 
     
     
       11. The device or apparatus according to claims  1 ,  2  or  7 , wherein the wire rope anchor or first anchor is spherical in shape. 
     
     
       12. The device or apparatus according to claims  1 ,  2  or  7 , wherein the window frame actuator is finger or foot operable. 
     
     
       13. The device or apparatus according to claims  1 ,  2  or  7 , further comprising a spring urging into a closed position and coupled to the window frame. 
     
     
       14. The device or apparatus according to claims  1 ,  2  or  7 , wherein the window frame actuator comprises a finger-operated pneumatic device coupled to the wire rope. 
     
     
       15. The device or apparatus according to claims  1 ,  2  or  7 , wherein the window frame actuator comprises a finger-operated hydraulic device coupled to the wire rope. 
     
     
       16. The device or apparatus according to claims  1 ,  2  or  7 , wherein the window frame actuator comprises an electromagnet in proximity to the wire rope anchor or first anchor. 
     
     
       17. The device or apparatus according to  claim 16 , wherein the window frame actuator further comprises a button-operable wireless device which transmits a signal to the electromagnet. 
     
     
       18. The device or apparatus according to  claim 16 , wherein the electromagnet is solar powered. 
     
     
       19. The device or apparatus according to  claim 16 , wherein the electromagnet is electric powered.
